About Velora

We build care that helps people live healthier and longer.

Velora is a digital healthcare provider focused on medically supported weight loss. We build products that make the patient journey smoother and help our care teams work more efficiently. Covering onboarding, payments and subscriptions, follow-ups, communication, knowledge content, and upcoming integrated care flows.

Your impact will save lives. What you build at Velora helps more people access effective, medically supported weight loss, reducing their risk of serious conditions like cardiovascular disease and other obesity-related complications. Research suggests obesity can shorten life expectancy by up to around 10–15 years, often with years of avoidable health struggles. Here, your work can help change that trajectory.

Why now:

We’re in a phase where we’re scaling and evolving both our internal platform (“Velora Tools”) and patient-facing functionality, such as portal experiences, information/FAQ, profiles and payments, notifications, and upcoming integrations (e.g., BankID and additional care flows).

How we work:

• We build for the long term: clear architecture, well-structured integrations, and a codebase that’s easy to maintain.
• Close collaboration across engineering, product, and design (Figma), with a strong focus on quality and usability.
• You’ll own medium-complexity tasks independently, with support from senior developers.
• Use Lovable to quickly showcase and demo ideas (rapid prototyping for stakeholders)

The challenge you’ll own

Ship a high-quality, performant, and intuitive platform for patients and clinicians. Building across frontend, backend, cloud, and integrations to deliver a seamless experience end-to-end.

What success looks like

After ~3 months (directionally):

• You’ve shipped multiple production improvements across both frontend and backend in our TypeScript stack.
• You’ve improved or extended at least one integration (e.g., Stripe or Firebase-related flows) with clear logging and solid error handling.
• You’re comfortable with our workflow: PRs, code reviews, and implementing design from Figma.

After ~6 months:

• You reliably own medium-complexity features end-to-end (UI → API → DB → configuration/deploy).
• You actively improve quality: testing, integration robustness, and developer experience (CI/CD, DX).
• You’re a strong partner to the team in making the platform more scalable and easier to evolve.

Key Responsibilities

Frontend (React & React Native

• Develop and maintain applications in React.
• Build responsive, cross-platform mobile UI with React Native.
• Implement business logic with TypeScript, React hooks, and modern React patterns.
• Integrate frontend with backend APIs.

Backend (Hono & Drizzle)

• Develop backend services with Hono on Bun..
• Design and maintain REST APIs.
• Implement business logic, validation, and authorization.
• Work with Drizzle ORM for database access.
• Design and evolve PostgreSQL schemas and migrations.

Integrations & Cloud

• Integrate third-party services like Stripe (payments, subscriptions, webhooks).
• Integrate external identity/banking services (e.g., BankID).
• Work with Firebase (auth, email verification, tokens, notifications).
• Deploy and maintain services on Google Cloud Platform (GCP).
• Manage environment configuration, secrets, and cloud resources.

AI, Tooling & Collaboration

• Work efficiently and responsibly with AI — use it to boost productivity and quality while applying judgment about where it helps and where it doesn't (correctness, privacy, and security matter in a healthcare context).
• You're free to choose your own editor and AI tooling — we don't mandate a specific setup.
• Collaborate with designers in Figma for accurate UI/UX implementation.
• Explore AI tools for development, testing, documentation, or automation.
• Participate in code reviews across both frontend and backend.

About you

Candidates must be placed in EU

Required Skills & Experience

• 2–4 years of professional development experience.
• Strong TypeScript skills (frontend + backend).
• Experience with React and modern frontend development..
• Experience with Node.js/Bun and building backend services (Hono, or similar like Express/Fastify/NestJS).
• Experience with PostgreSQL.
• Hands-on experience with Drizzle (or a similar ORM)..
• Experience integrating REST APIs.
• Git and collaborative workflows (PRs, reviews).
• Comfortable using AI-assisted tooling effectively and responsibly.
• Ability to implement UI from Figma.
• Familiar with Agile/Scrum.

Nice to have

• React Native (or other cross-platform mobile framework) experience.
• Stripe integrations (payments/subscriptions/webhooks).
• BankID (or similar).
• Monorepo experience (e.g., Bun workspaces, Turborepo).
• GCP (e.g., Cloud Run / Cloud Build).
• Firebase Authentication.
• Basic Docker and CI/CD.
• Testing (unit/integration/e2e).
• Posthog experience.

Personal qualities

• Strong problem-solving and analytical thinking.
• Self-driven, takes ownership.
• Great communication and collaboration skills.
• Curious about new tools/frameworks and AI-powered workflows.
• Product-minded and quality-focused.

What we offer

• Build work that actually matters: You’re not optimizing vanity metrics, you’re building product that helps people live healthier, longer lives.
• Ship fast, see it used immediately: Your work lands in real patient and care-team workflows within weeks, not quarters. Tight loops. Real feedback. Real outcomes.
• Full-stack TypeScript, Go end-to-end across React + React Native, Hono on Bun, Drizzle, PostgreSQL, and GCP. You'll ship features that touch UI, APIs, data, and production, like it should be.
• Hard problems in a high-trust domain: Payments and subscriptions (Stripe webhooks), identity and onboarding (Firebase, BankID), clinical workflows, reliability, and UX where mistakes actually matter.
• Taste + quality, then speed: We obsess over whole-journey polish, performance, resilience, and clean UX. We ship small, review carefully, and keep the bar high.
• Real ownership, real growth: You’ll own meaningful chunks of the product, not “tickets.” You’ll be trusted early and you’ll level up fast with senior support.
• A team that builds, not talks: Low ego, high standards. We care about shipping, learning, and making the product better every week.
• Compensation that matches the ambition: Competitive salary (and room to flex based on scope and impact).
